"Everyone is too afraid," said Citizen Action Volunteer Mary Clark, "I don't know what's happened, but none of the workers would actually dare to come out and speak, but two workers gave us anonymous comments."

The day of action calls for increasing the minimum wage to $15 an hour. Protestors point to the National Employment Law Project report showing the median age of fast-food workers. It says they're older than 28 and more than one-quarter are raising at least one child.

"It's about raising awareness," said Citizen Action volunteer Amy Fleming. "It's about letting people know that people cannot survive on minimum wage. They cannot survive on the rules and regulations of fast food places."

Protesters said they would be willing to pay more for fast food if that meant a higher wage for its employees.
